Cytogenetic studies in four cultivated Amaranthus [Amaranthaceae] species
In the present study, the chromosomes numbers were confirmed, 2n = 34 for Amaranthus cruentus Linnaeus, 1759, and 2n = 32 for A. hypochondriacus Linnaeus, 1753, A. mantegazzianus Passer, 1864, and A. caudatus Linnaeus, 1753. The distribution and variability of constitutive heterochromatin were detai...

The distribution and variability of constitutive heterochromatin were detailed using DAPI-CMA3 banding technique. The position of the nucleolus organizer region [NOR] was observed using Ag-NOR banding [active loci] and fluorescent in situ hybridization [rDNA-FISH] in the four Amaranthus species. Variations in the amount of constitutive heterochromatin were detected both within the species and between them, with DAPI-CMA3 stain. One chromosome pair having a NOR was found in each studied accession, with exception of A. caudatus cv. EEA INTA Anguil. This accession presented four rDNA loci [FISH], being active two of them [Ag-banding]. | ||
